Objective:To evaluate the value of neutrophil to lymphocyte and platelet ratio (N/LPR) for predicting 28-day mortality in sepsis patients.Methods:A retrospective analysis was conducted. The clinical data of 154 sepsis patients admitted to intensive care unit (ICU) of the Affiliated Hospital of Jiangsu University from June 2017 to June 2020 were enrolled. The time of first diagnosis of sepsis in ICU was taken as the research starting point, and the death or 28 days as the end point. The 28-day outcomes of patients were recorded. The counts of peripheral blood neutrophil (NEU), lymphocyte (LYM) and platelet (PLT) were collected from all the enrolled patients within 3 days after diagnosis of sepsis. The ratios of N/LPR and NEU/LYM (NLR) were calculated respectively. The differences of N/LPR and NLR between survival group and death group were compared. Receiver operating characteristic (ROC) curve analysis was used to analyze the value of N/LPR and NLR on predicting the 28-day mortality of sepsis patients. According to the best cut-off value of ROC curve analysis, the 28-day mortality of patients with sepsis was analyzed by subgroup analysis, and the 28-day cumulative survival of patients with sepsis was analyzed by Kaplan-Meier survival curve.Results:Of the 154 sepsis patients, the patients with age < 18 years, pregnancy, blood disease, taking aspirin or other antiplatelet drugs within 1 week, taking leucocyte drugs within 1 week, length of ICU stay < 3 days and incomplete data were excluded. Finally, 50 patients were enrolled. Among them, 30 patients survived on the 28th day and 20 died. Compared with the survival group, the levels of N/LPR and NLR in the death group were significantly increased (N/LPR: 23.85±11.99 vs. 12.41±5.25, NLR: 17.83±8.69 vs. 10.75±3.63), with statistical differences (both P < 0.01). ROC curve analysis indicated that the area under ROC curve (AUC) of N/LPR for predicting 28-day death of sepsis patients was 0.827, it was higher than that of NLR (AUC = 0.762). Base on N/LPR≥15.48 as a predictor of cut-off value of death in 28 days of sepsis patients, the sensitivity was 75.0% and the specificity was 80.0%, respectively. Base on NLR≥10.65 as a predictor of cut-off value of death in 28 days of sepsis patients, the sensitivity was 75.0% and specificity was 56.7%, respectively. Subgroup analysis showed that the 28-day mortality in the patients with N/LPR≥15.48 ( n = 21) was significantly higher than those with N/LPR < 15.48 ( n = 29; 71.4% vs. 17.2%, χ 2 = 14.901, P < 0.01); and the 28-day mortality in the patients with NLR≥10.65 ( n = 28) was also significantly higher than those with NLR < 10.65 ( n = 22; 53.6% vs. 22.7%, χ 2 = 4.884, P < 0.05). The results were consistent with Kaplan-Meier survival curve analysis. Conclusion:Peripheral blood N/LPR has a good predictive value for 28-day mortality of sepsis patients, and which is better than NLR.

Objective:To investigate the correlation between 6-phosphofructo-2-kinase/fructose-2, 6-biphosphatase 3 (PFKFB3) and the inflammatory activation of polymorphonuclear myeloid-derived suppressor cell (PMN-MDSC) in acute myocardial infarction (AMI), and to evaluate the effect of intervention targeting PFKFB3 on the inflammatory activation of PMN-MDSC during AMI.Methods:① Clinical trial section: a observational study was conducted. The patients with acute coronary syndrome (ACS) admitted to Zhenjiang Fourth People's Hospital were enrolled, and they were divided into AMI group and non-AMI group according to clinical diagnosis. The peripheral venous blood of the two groups was collected to detect the proportion of PMN-MDSC, and the expression of PFKFB3 gene in mononuclear cells was detected by real-time quantitative polymerase chain reaction (RT-qPCR). ② Basic experiment section: a total of 30 male C57 mice (aged 6-8 weeks) were divided into normal control group ( n = 5), Sham group ( n = 5), AMI model group ( n = 10) and PFKFB3 inhibitor PKF-15 intervention group ( n = 10) according to random number table method. The AMI model of mice was reproduced by left anterior descending coronary artery (LADCA) ligation, and the mice in the Sham group did not attach the artery after thoracotomy. The PKF-15 intervention group was intraperitoneally injected with PKF-15 (20 μg/g) at the same time of LADCA ligation. Normal control mice did not receive any treatment. Peripheral venous blood and myocardial tissue of mice were collected 24 hours after modeling. Both the circulating PMN-MDSC ratio and the infiltration of PMN-MDSC in myocardial tissue were detected. After staining with hematoxylin-eosin (HE), the degree of inflammatory damage in mouse myocardial tissue was observed under light microscopy. PMN-MDSC were isolated from mice with flow cytometry, and the gene expressions of PFKFB3 and inflammatory factors were measured by RT-qPCR. Results:① Clinical trial section: the circulating PMN-MDSC ratio of patients in the AMI group ( n = 25) was significantly higher than that in the non-AMI group [ n = 20; (8.53±0.96)% vs. (1.13±0.39)%, P < 0.01], and PFKFB3 gene expression in the peripheral blood mononuclear cells was also increased (2 -ΔΔCt: 1.18±0.19 vs. 0.96±0.16, P < 0.01). Pearson correlation analysis showed that circulating PMN-MDSC ratio was positively correlated with PFKFB3 gene expression in mononuclear cells in AMI patients ( r = 0.608, P = 0.001). ② Basic experimental section: the circulating PMN-MDSC ratio and the infiltration of PMN-MDSC in myocardial tissue of AMI mice were significantly higher than those in the normal control group and Sham group. PFK-15 intervention could reduce the ratio of PMN-MDSC in the peripheral blood and myocardial tissue of AMI mice [(26.33±5.27)% vs. (75.12±5.02)% in peripheral blood, (20.87±2.97)% vs. (35.28±4.36)% in myocardial tissue, both P < 0.01]. Under light microscopy, the myocardial cells in the AMI modal group were disordered and a large number of inflammatory cells infiltrated. PFK-15 intervention could maintain a normal arrangement of cardiomyocytes and reduce the infiltration of inflammatory cells. The gene expression levels of PFKFB3 in the peripheral blood and myocardial tissue as well as the inflammatory factors in the myocardial tissue of AMI mice were significantly higher than those in the normal control group and Sham group. PKF-15 intervention could effectively reduce the gene expression levels of PFKFB3 in the peripheral blood and myocardial tissue as well as the inflammatory factors in the myocardial tissue of AMI mice [PFKFB3 mRNA (2 -ΔΔCt): 1.01±0.09 vs. 1.40±0.12 in peripheral blood, 0.95±0.09 vs. 1.47±0.10 in myocardial tissue; myocardial tissue tumor necrosis factor-α (TNF-α) mRNA (2 -ΔΔCt) was 14.55±3.99 vs. 29.66±3.90, interleukin-1β (IL-1β) mRNA (2 -ΔΔCt) was 8.72±1.35 vs. 18.53±2.43, IL-6 mRNA (2 -ΔΔCt) was 11.87±2.97 vs. 19.82±4.32, all P < 0.01]. Conclusions:The activation of PFKFB3 is closely related to the inflammatory activation of PMN-MDSC during AMI. Inhibition of PFKFB3 activity can inhibit the inflammatory activation of PMN-MDSC and reduce myocardial inflammatory injury.

Objective:To study the predictive value of BAT score for the prognosis of patients with spontaneous intracerebral hemorrhage (sICH).Methods:A retrospective analysis of 93 sICH patients in the Emergency Department of the Second Affiliated Hospital of Wannan Medical College from January 2018 to December 2020 was conducted, and the patients were classified into the good prognosis group ( n=34) and the poor prognosis group ( n=59) according to the Glasgow Outcome Score (GOS) 3 months after the discharge. Clinical data such as basic data of patients, admission vital signs, laboratory indicators, National Institute of Health stroke scale (NIHSS) score and BAT score and other clinical data of the two groups were compared. Multivariate logistic regression was used to analyze the risk factors affecting poor prognosis of sICH patients. The receiver operating characteristic (ROC) curve was drawn to analyze predictive value of BAT score for poor prognosis of sICH patients. Results:The admission systolic blood pressure, white blood cell count, hypertension complications, emergency BAT score and NIHSS score of patients in the poor prognosis group were significantly higher than those in the good prognosis group ( P<0.05). Multivariate logistic regression analysis indicated that the admission systolic blood pressure ( OR=1.024, 95% CI: 1.002~1.046, P=0.035) and emergency BAT score ( OR=2.640, 95% CI: 1.445-4.825, P=0.002) could accurately predict the poor prognosis of sICH patients. ROC curve analysis showed that the area under ROC curve (AUC) of BAT score was 0.792, the sensitivity was 79.3%, and the specificity was 76.5%. The AUC of systolic blood pressure for predicting poor prognosis of sICH patients was 0.701, and the sensitivity was 55.2%, and the specificity was 88.2%. The AUC of BAT score combined with systolic blood pressure for predicting poor prognosis of sICH patients was 0.835. Conclusions:BAT score and admission systolic blood pressure could more accurately predict poor prognosis of sICH patients. The combination of them had a higher efficacy in predicting poor prognosis of sICH patients after 3 months.

ObjectiveThe theory of homotherapy for heteropathy is one of the classical rules in traditional Chinese medicine. Taking this theory as a breakthrough point, this study employed gas chromatography-mass spectrometry (GC-MS) to elucidate the mechanism underlying the therapeutic effects of Zhuyuwan on both intrahepatic cholestasis (IC) and ulcerative colitis (UC) from the viewpoint of serum metabolic homeostasis. MethodsThe rat models of α-naphthylisothiocyanate (ANIT)-induced cholestasis and 2,4,6-trinitro-benzenesulfonic acid (TNBS)-induced UC were treated with low (0.6 g·kg-1) and high (1.2 g·kg-1) doses of Zhuyuwan by gavage. In the experiment regarding IC, 24 Sprague-Dawley (SD) rats were randomly assigned into four groups: normal, ANIT model, low-dose Zhuyuwan, and high-dose Zhuyuwan. In the experiment regarding UC, 24 SD rats were randomly allocated into four groups: normal, TNBS model, low-dose Zhuyuwan, and high-dose Zhuyuwan. Firstly, the two disease models and the intervention effects of Zhuyuwan on the two diseases were evaluated based on serum levels of biochemical indicators [alanine aminotransferase (ALT), aspartate transaminase (AST), γ-glutamyltranspeptidase (γ-GT), and total bile acid (TBA)], colon damage score, colon weight index, disease activity index, and histopathological changes in rats. Secondly, the rat serum samples were analyzed by gas chromatography-mass spectrometry (GC-MS) to screen the common core pathways of the two disease models, and the expression of core genes in the pathways was determined by Real-time PCR, on the basis of which the biological mechanism of the treatment of the two disease models by Zhuyuwan was ultimately elucidated. ResultsThe results of the experiment regarding IC showed that the ANIT model group had higher ALT, AST, γ-GT, and TBA levels than the normal group (P<0.01). Compared with the ANIT model group, the low-dose Zhuyuwan group showed declined ALT and TBA levels (P<0.01) and the high-dose Zhuyuwan group showed lowered ALT, TBA, AST, and γ-GT levels (P<0.01). The results of the experiment regarding UC showed that compared with the normal group, the TNBS model group presented increases in the colonic damage score, colon weight index, and disease activity index (P<0.01). Compared with the TNBS model group, the low-dose Zhuyuwan group showcased declines in colon weight index (P<0.01) and disease activity index (P<0.05), and the high-dose Zhuyuwan group showed reductions in the colon damage score, colon weight index, and disease activity index (P<0.01). GC-MS metabolomics analysis combined with qRT-PCR demonstrated that Zhuyuwan had a similar inverse regulatory effect on arginine metabolism disruption in the above two disease models. ConclusionZhuyuwan exhibited definite therapeutic effects on both IC and UC, and the regulation of arginine biosynthesis pathway is the core mechanism for the treatment of both diseases by Zhuyuwan.
